We are installing a large (approx. 10' x 15'), historic, plaster, newly conserved, 3-d topographic map in one of our galleries. I am looking for a proximity motion detector that uses a curtain protection pattern and emits an audible alarm to help deter folk with long arms and inquisitive fingers from touching the surface of the map. We will not be able to link this proximity alarm into the building's alarm system so it must be a free standing unit. I am interested in recommendations of systems or units that have worked well with wall mounted objects in other museum galleries. Thanks, Julianne -- Julianne Snider Asst.
